closet temps

hay guys what wll it do to the plant if closet temps hit low 90 throught the day and low 80 during the night (lights off) that seems to be as good as i can get it without leaving the door open all day ideas would be great

also i have two bag seeds one is growing great and the other is turning brown and yellow after two week it has 2 leafes green and two leafes dead no camera stem is white any info would help my ph is 6.0 6.5 water every other day heat is 90 for the most part and i have t5 4ft 8 bulb 12 inch away

withou knowing more it sounds like you need more ventilation. Where is the heat coming from, that light isn't putting out that much heat.

the closet is 5x5x9 i have a sunblaze 48 t5 with blue light on 20/4 lighting
one floor fan for air curculation all im asking is what is the effects of high temps meaning will i get all male if i grow in 90* closet thats all im asking my second plant seems to be doing better flushed it the other day and its fixed

no replys? what dose heat stress at 90* do to the end product

Be patient. Other people have problems in the grow room to deal with too :jointsmile: Might not have time to help out... or they're just plain busy :smokebong:

High temps exacerbate other problems, and yes, the pale patches are likely a secondary effect of the heat.
Chlorophyll starts to break down in the mid 90s. Enzymatic processes grind to a halt. No amount of food, water, or foliars will solve the problem if the plant lacks the enzymes to assimilate nutrients.

I read somewhere that the perfect "lights on" temp is 77.2...The same person said that THC production starts to slowly diminish at temps above 80 degrees without CO2,and much more noticeably at temps above 85 degrees...
Temps 90 degrees and above without heavy CO2 can be stressful enough to cause a plant to hermie and would also seriously affect the plants THC production...

The normal amount of CO2 in our outdoor atmosphere is 0.03-0.04% CO2...

Not a prob jrleister...,

Good luck with your grows!!!:420thought:

Well, you certainly aren't going to get the MOST out of this grow if you can't get the temps down, but if you have females you'll still get buds... They'll just be fluffy & airy, and probably not as potent as they could be.
Circulation is good, but you need some fans pulling fresh cool air into the grow space and some fans pulling hot air out.. If you can do that, your temps will drop into the high 70's- low 80's and your plants will love you for it. :)
